Nurture becomes nature: the evolving place of psychology in the theory of evolution

The thesis here presented establishes a triple parallelism between biology and psychology. First, through Haeckel's recapitulation theory as the source of freudian and jungian psychology. Second, from the reductionist view of science to the new phenomenology of evolutionary developmental biology. Third, by overcoming the reductionist paradigm in biology through the Extended Synthesis and in psychology though the revisited archetype theory. By establishing these parallelisms, the thesis faces the nature vs. nurture debate on three epistemological levels, in which the external and internal levels are being mediatied by a middle one. This turns the dualistic debate into a heuristic paradigm aimed to resolve any irreducible dualism inherent in the reductionist view
